Does addition of low-level laser therapy (LLLT) in conservative care of knee arthritis successfully postpone the need for joint replacement?

The objective of this study was to evaluate whether the addition of low-level laser therapy into standard conventional physical therapy in elderly with bilateral symptomatic tricompartmental knee arthritis can successfully postpone the need for joint replacement surgery.

Comparison of light penetration of continuous wave 810 nm and superpulsed 904 nm wavelength light in anesthetized rats

This study examines the 2012 publication by Joensen et al. Transmission through an anesthetized rat skin flap with a continuous wave 810 nm laser and a superpulsed 904 nm laser. The authors conclude that penetration through tissue of 810 nm wavelength light is greater than that of superpulsed 904 nm light. They suggest that the [...]
